The Relationship Between Desulfurization And Forging Temperature In Rotary Kiln

A method for desulfurizing a hot-metal, which reutilizes a desulfurization dross formed through a KR hot-metal desulfurization treatment as a desulfurizing agent to thereby reduce the cost for hot-metal desulfurization and decrease the amount of slag generated, and also contributes to the solution of an environmental issue through the decrease of the amount of slag.
